Landslide Remediation

Tumut

Following a series of heavy rainfall events and the associated rise of Tumut River, extensive landsliding of fill occurred at the access roadway to the William Hudson camping ground.

Tumut Council sought advice from SCE for economic methods of the required repairs. Subsequently, after an initial investigation, SCE advised that the most economical solution would involve the realignment of the roadway into the hillside in combination with a limited amount of remediated fill. A major constraint to the realignment was the proximity of the roadway to the National Park and an existing Telstra Cable.

SCE recommended that a soil nail system was the best solution to stabilise the realigned excavation so that the excavation could be stable and not impinge on the National Park or Telstra cable.
